Hyundai R250LC-7 Swing Bearing 2ton excavator machine bearing Slewing ring 5 axis cnc CROSS ROLLER BEARING

The Hyundai R250LC-7 is a 25-ton class hydraulic excavator produced by Hyundai Construction Equipment. For the swing bearing or slewing ring used in the R250LC-7 excavator, it is important to note that the specific model and specifications may vary. However, I can provide you with some general information about swing bearings used in similar-sized excavators:

1. slewing ring bearing Type:
The swing bearing used in the Hyundai R250LC-7 excavator is typically a crossed roller Slewing Bearing or a four-point contact ball slewing bearing. Crossed roller bearings feature crossed cylindrical rollers arranged in a crisscross pattern between the inner and outer rings, providing high load capacity and rotational accuracy. Four-point Contact ball bearings have a single row of balls with four contact points, offering both axial and radial load-carrying capabilities.

2. Size and Specifications:
The exact size and specifications of the swing bearing for the Hyundai R250LC-7 excavator can vary. It depends on factors such as the required load capacity, dimensions, gear module, gear type (spur gear or helical gear), and gear ratio. These specifications are determined based on the specific requirements of the excavator model.

When looking for a replacement swing bearing for the Hyundai R250LC-7 excavator, it is crucial to ensure that the new bearing matches the required specifications, dimensions, and load capacities. It is recommended to consult the manufacturer's documentation or reach out to authorized dealers or suppliers who specialize in Hyundai excavator parts for accurate information and compatible replacements.

Slewing Bearing is a kind of large bearing that can withstand large axial load, radial load and overturning moment and other comprehensive loads. This type of bearing generally has mounting holes, lubricating oil holes, sealing devices, internal gears or external gears, so It can make the main engine compact, easy to rotate, easy to install and easy to maintain. The slewing bearing has Four-point Contact ball bearings without gear, external gear and internal gear, double disc Angular Contact Thrust ball bearings, crossed Cylindrical Roller Bearings, Crossed Tapered Roller Bearings and three-row cylindrical roller Combined bearings and other structural types. Four-point contact ball bearings have high static load capacity, crossed cylindrical roller bearings have high dynamic load capacity, and crossed tapered roller bearings have high dynamic load capacity. It has larger support rigidity and higher rotation accuracy.
